Boil Water Notices

Boil Water Notice Lifted for Peketa August 2nd

Current Boil Water Notices: Ocean Ridge, Suburban and East Coast 

If you are on any of these water supplies please boil all drinking/cooking water for at least 1 minute before you use it. This includes water for:

  • Drinking
  • Cooking
  • Making Ice
  • Brushing Teeth
  • Washing Dishes

If you have friends or relatives living in these areas please help pass the word by checking to make sure they know they need to boil their water.

We know living with Boil Water Notices can be frustrating. We’re doing everything we can to improve water quality and remove the notices as soon as possible whilst keeping people healthy. more information about each current boil water notice can be found below.

We’ll update people on where how long works are expected to take as soon as we can.

Ocean Ridge:

A BWN was put in place on 27 December 2017. We estimate that the notice will be able to be lifted by October 2018 at the latest.  

Results of testing from 20 December 2017 identified contamination in the reticulation. Chlorine treatment of the scheme at the reservoir was initiated on 22 December 2017 as soon as Council was notified of the test results . Residents were notified on 27/28 December by maildrop, Facebook and website updates. The lack of postboxes that meant some residents did not receive the maildrop notice.

UV treatment is applied to the bore water that is delivered to the reservoir. Due to the way the UV treatment works there is no protection should contamination occur after the treatment process. Contamination most likely occurred in the reservoir that was subject to emergency repairs post-earthquake. Further remedial work is now needed to the reservoir and liner, this work is estimated to take between 3 and 6 months. 

Once consecutive complying test results are received and remedial works undertaken lifting the BWN can be considered subject to agreement by Canterbury DHB.

Suburban:

A boil water notice has been in place since the November 2016 earthquake  and will remain in place for the foreseeable future until decisions about the future of the scheme are made. 

Post-earthquake investigations have identified intake damage and source changes on top of what was already limited protection. Suitable protection would be provided by intake improvements, storage and treatment.

Once improvement works are undertaken and consecutive complying test results are received lifting the BWN can be considered subject to agreement by Canterbury DHB.

East Coast: 

The East Coast scheme is a very large rural supply used predominately for stock. A boil water notice has been in place since before the November 2016 earthquake and will remain in place for the foreseeable future until decisions about the future of the scheme are made. 

Post-earthquake investigations highlighted the limited protection measures. Due to it's size, it would not be practical or efficient to treat the entire scheme. Discussions with the scheme committee and Canterbury DHB  are underway to look at future options including the potential to classify the scheme as a Rural Agricultural Supply.

Once decisions are made, required improvement works undertaken and consecutive complying test results are received, lifting the BWN can be considered subject to agreement by Canterbury DHB.

Note about the Kincaid water scheme:

The Kincaid scheme shuts down automatically after heavy rain, limiting residents supply to their domestic tank.
